fix(lib): allow unsafe_op_in_unsafe_fn on wasm32 for wit_bindgen 0.36

Same suppression as in fai/platform's modules/echo: wit_bindgen
0.36's export! macro expands into unsafe fns whose bodies call
further unsafe fns without explicit unsafe blocks, and Rust 2024
makes that an error under -D warnings. Drop once wit_bindgen
ships a fix.

Gated on target_arch wasm32 so the host build (tests, plan
validation) stays strict.
